Yeah, whatever it's doing, the math only means the battery itself is getting about 25w charge rate (that's why I included a accu battery screenshot)
I did see it spike to 5.5A though which puts it in 25+ territory.
I presume to get full 45w rate it needs to be at low enough battery percentage as well.
Tldr, this is an amazing charger that charges phones quickly! At an AMAZING price. Good luck finding even a 25w charger With 8ft cable at 9$ that also has a normal USB port!
I wished there were more, but there was only one where I was at.
